Green tourmaline is one of the most captivating gemstones in the world, renowned for its beautiful green hues and remarkable clarity. This gemstone is a popular choice for jewelry, and its stunning shades make it highly sought after by collectors and gem enthusiasts. However, not everyone is aware of the various locations where green tourmaline is found. In this article, we will explore the regions around the world where this beautiful gem is sourced, and why these locations are crucial for its formation and extraction.
What is Green Tourmaline?
Before we delve into where green tourmaline is found, let’s first understand what this gemstone is. Tourmaline is a complex silicate mineral composed of boron, aluminum, and various other elements, which can lead to a wide range of colors. Green tourmaline specifically gets its vivid green color from the presence of iron and sometimes vanadium. The intensity of its color can vary from light, almost pastel greens, to deep, forest-like greens, making it a versatile gemstone for many types of jewelry.
Major Locations Where Green Tourmaline is Found
Green tourmaline is not just one of the rarest but also one of the most sought-after types of tourmaline. It can be found in several locations worldwide. Here are some of the most significant sources of green tourmaline:
1. Brazil
Brazil is one of the largest producers of tourmaline, and it is well-known for its green tourmaline deposits. The state of Minas Gerais in Brazil is especially famous for its rich variety of tourmaline, including the prized green varieties. Some of the most stunning green tourmalines are mined here, and the gemstone from Brazil is considered to be among the finest in the world.
The area of Paraíba is particularly famous for producing tourmaline that comes in intense green hues. While the Paraíba tourmalines are most famous for their bright blue varieties, green tourmalines from this region are still highly prized for their color and clarity.
In Minas Gerais, other regions like Capelinha and Governador Valadares are known for their high-quality green tourmaline as well. These areas produce stones that range from lighter greens to deeper, richer hues, making Brazil an essential part of the green tourmaline market.
2. United States
The United States is another major source of green tourmaline, with Maine and California being the primary states where the gemstone is found. The famous Newry area in Maine has yielded high-quality green tourmaline in the past. These stones are often well-formed and exhibit a pleasing green color, often with a slight bluish undertone.
California has also produced notable green tourmalines, particularly from locations like San Diego County and Pala. These areas are known for producing a variety of tourmaline colors, including green. Pala is especially significant, as it is a historically rich mining area for gemstones, including tourmaline.
The U.S. tourmalines are often cut into smaller stones, and the green tourmalines mined here tend to have a more subdued, earthy green color compared to some of the more vivid varieties from other countries.
3. Afghanistan
Afghanistan is another key location for green tourmaline mining. Known for producing gemstones of exceptional quality, Afghanistan has long been a source of beautiful green tourmaline. The Nuristan province in Afghanistan is especially famous for its high-quality green tourmalines, which often have a deep, rich green color.
The Afghan green tourmalines are typically well-formed and have excellent clarity. Their deep green hues are highly valued in the gemstone market, and they often feature unique color zoning, making them especially appealing to collectors and jewelers.
4. Mozambique
In recent years, Mozambique has gained recognition as a significant source of green tourmaline. The country has vast deposits of tourmaline in various colors, and green tourmaline is one of the most sought-after types. The region of Tete is especially known for producing high-quality green tourmaline, and it has quickly become one of the primary sources for tourmaline in the world.
Mozambique’s green tourmaline tends to feature vibrant, rich green colors, making it highly popular in both the jewelry and collector markets. The country’s mines are relatively new compared to Brazil or Afghanistan, but they have rapidly established a reputation for producing some of the most beautiful green tourmaline gemstones.
5. Africa (Other Countries)
In addition to Mozambique, other African countries have been known to produce green tourmaline, although in smaller quantities. Nigeria, for instance, is known for producing tourmaline in a variety of colors, including green. The Ogun state in Nigeria has produced some remarkable green tourmalines, which have gained popularity for their clarity and vibrant color.
Other African regions, including Kenya and Tanzania, have also been sources of green tourmaline, although they are not as well-known for this specific variety of the gemstone. Nevertheless, the presence of green tourmaline in these regions adds to Africa’s importance as a gemstone hub.
6. Pakistan
Pakistan, particularly the Kunar Valley, is also home to green tourmaline. The country’s mountainous regions are rich in minerals, and gemstones like tourmaline are found in abundance. The green tourmaline from Pakistan often exhibits a beautiful olive-green color, making it distinct from other varieties found in different parts of the world.
The green tourmaline mined in Pakistan is known for its clarity and unique color, making it highly prized by collectors and jewelers alike.
7. Other Notable Locations
While the above countries are the primary producers of green tourmaline, there are other smaller deposits in various regions of the world. These include places like Sri Lanka, which is known for producing fine gemstones in various colors, and Thailand, which has yielded some green tourmaline stones, although not in large quantities. Tourmaline has also been discovered in small amounts in countries like Madagascar and Australia, although these are not primary sources for green tourmaline.
Why is Green Tourmaline So Special?
Green tourmaline stands out due to its vibrant and varied color spectrum, which can range from light mint green to dark forest green. The primary element responsible for its color is iron, and sometimes vanadium, which gives the stone its distinctive green hue. These elements are found in the geological conditions that exist in specific regions, which is why green tourmaline is often found in certain locations around the world.
In addition to its stunning color, green tourmaline is also valued for its durability. With a hardness of 7-7.5 on the Mohs scale, green tourmaline is relatively resistant to scratches and wear, making it an excellent choice for everyday jewelry like rings, necklaces, and bracelets.

From the rich deposits in Brazil and the United States to the vibrant stones from Mozambique and Afghanistan, the unique colors and clarity of green tourmaline continue to captivate gem enthusiasts and collectors alike. Whether you’re looking for a bright, minty green or a deep, forest-like hue, green tourmaline is a versatile and beautiful gemstone that is sure to enhance any jewelry collection.
